BLANK-HOLDER FOR PUNCHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent N0.382,911, dated May 15,1888.

Application filed September 5, 1887. Serial No. 248,873. No model.)

To all whom it may concern;

Be it known that 1, RALPH J. SHIPLEY, of \Vaterbury, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Holdersfor Sheet-Metal Blanks for Punching-llIaehines;and the following is declared to be a description of the same.

My invention relates to a two-part case or sheath attachment for ametal-punching machineto receiveand hold theblanksaspunched, one portionof said case being removable for transferring the blanks to aforming-machine, and an empty case is inserted in its place. Theseimprovements are especially applicable to metallic blanks for makingpaper-fasteners. The blanks as punched out of the sheet metal arereceived into the stationary part of the case, the interior of whichcorresponds in shape to the blank, and there is a friction-plate whichpresses against the blanks sufficiently to keep them from falling. Theremovable sheath is connected to the stationary case, and to receivetherefrom the blanks as they pass down the stationary case. This sheath,when full of blanks, is removed and conveyed to a formingmachine and anempty sheath inserted in its place.

In the drawings, Figure 1 represents a punching'machine with myimprovement connected thereto. Fig. 2 is an elevation of the case andsheath. Fig. 3 is a vertical section at the line w m of Fig. 1, and Fig.4 is a plan view of the case detached from the punchingmachine. Figs.2', 3, and t are in larger size.

Similar letters of reference in the various figures indicatecorresponding parts.

A represents the frame-work of the punching-machine, which is of anydesired character. B is the sliding head-block, C the male die, and Dthe female die. The sheet metal is fed to the dies by the rollers 70 It.

Directly below the female die D, and secured 4 by the pins g, coiledsprings j, and bowed bearing-bars h, secured upon the case.

F represents a hollow slotted sheath whose upper end is made as adovetail block, F, and said block fits a corresponding dovetail recessin the base of the case E, and is held in place between the plated andthe swinging arm 2'. The sheath F is slotted at h, and there is a springblock or support, 9, movable lengthwise of said slot, upon which theblanks lie as they are fed down into the sheath, and this support ispressed down by the blanks as they accumulate.

The operation is as follows: The blanks as punched from the sheet ofmetal are forced down into the openingf, and they are kept in positionby the slight pressure of the presserbar G upon their edge; but they arenot held firm enough to prevent the blanks descending as they accumulatein the slot 1. After the case E is filled the blanks press automaticallyinto the sheath F F, and they are supported by the yielding holder whichdescends as the sheath fills up with blanks. sheath F F is full ofblanks, the arm 2" is swung aside and the sheath removed and an emptyone inserted into its place to be filled, and the full sheath is removedto a machine for bending or forming the fastening or other articles. Byinverting the sheath in such forming-machine it can be held in place byits dovetail block F-for example, as illustrated in my application No.248,874., filed of even date here with.

I claim as my invention-- 1. The combination, with a sheet metalpunchingmachine, of a slotted case for receiving the blanks as cut out,and apresser-bar for applying friction to the edges of such blanks, and aremovable sheath below the slotted case for receiving the blanks and inwhich they are conveyed away, substantially as set forth.

2. The combination, with a sheet metalpunching machine, of the slottedcase E, the friction-bar G, pins 9, coiled springs j, bear ing-bars h,the plate t, swinging arm t", and a sheath, F, having a dovetailed blockto be removably connected to the case E, substantially as set forth.

'3. In a sheet-metal-punching machine, the

combination of the slotted case E, the lower When the and springs end ofwhich has a dovetail groove, With the 5. The combination of a slottedcase for redovetailed block F and sheath F, adapted to ceiving blanksfrom a punching-machine, with be connected to said case E, thefriction-bar G, alongitudinallyslotted sheath detachably confor pressingsaid bar against the neoted with said slotted case for receiving the [5blanks, and the holder 9 in the blanks therefrom, substantially asdescribed.
